ZL50050GAC ZARLINK [Zarlink Semiconductor Inc], ZL50050GAC Datasheet - Page 19

• Manufacturer Part Number: ZL50050GAC
• Description: 8 K-Channel Digital Switch with High Jitter Tolerance, Per Stream Rate Conversion (2, 4, 8, 16, or 32 Mbps), and 32 Inputs and 32 Outputs
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

The modes in which one port operates in 32 Mbps Mode while the other port operates in Non-32 Mbps Mode allow
data rate conversion between 32.768 Mbps and 16.384 Mbps without loss to the switching capacity.
1.1
The ZL50050 can be configured as an 8 K by 8 K non-blocking unidirectional digital switch, a 4 K by 4 K
non-blocking bi-directional digital switch, or as a blocking switch with various switching capacities.
1.1.1
Because the input and output drivers are synchronous, the user can combine input Backplane streams and input
Local streams as well as output Backplane streams and output Local streams to increase the total number of input
and output streams of the switch in a unidirectional configuration, as shown in Figure 3.

1.1.2
Another typical application is to configure the ZL50050 as a non-blocking 4 K by 4 K bi-directional switch, as
shown in Figure 4:

1.1.3
The ZL50050 can be configured as a blocking bi-directional switch if it is an application requirement. For example,
it can be configured as a 6 K by 2 K bi-directional blocking switch, as shown in Figure 5:
